I just made my third site using GP Premium live yesterday only to discover that the header background image doesn’t display on a PC using either Chrome or Firefox. It looks fine on my Mac with Firefox or Safari. Site identity and flaoting menu appear, but not the background image. Settings are: No Repeat, Cover, Attachment.
Is there a simple solution? (I’m an experienced WordPress user and have built 4 WP websites but only use the built-in tools–no extra coding.) I looked for free or online emulators but couldn’t find anything besides mobile emulators mentioned on a Google developers page.
Thanks.
